MorningStar ReadyShunt Battery Monitor & DC Current Sensor Review
The ReadyShunt represents a significant advancement in battery monitoring technology by eliminating the complexity traditionally associated with shunt-based current measurement systems. The dual-input design with 0.4% measurement accuracy provides professional-grade monitoring capabilities while the automatic LiveView integration removes the need for separate monitoring software or third-party devices that often complicate system installation and maintenance. For solar installations requiring precise battery management, particularly those with lithium batteries or multiple charging sources, the ReadyShunt delivers essential SOC accuracy and system coordination capabilities that optimize both performance and battery longevity.
